Even against a person's best efforts cotton clothing, such as T-shirts and pants, can shrink. According to Cotton Incorporated (see reference 3), cotton will shrink after the first wash because a large amount of tension is applied to the fibers during construction. Once the cotton piece is washed, these fibers relax and will shrink. It is possible to stretch or "unshrink" a cotton item to bring it back to its original shape and form.

Step 2

Place the cotton garment into the bucket, making sure that it is completely immersed.
Step 3

Allow the piece to soak for 15 minutes. This will help relax the fibers once again, which will make them susceptible to stretching or "unshrinking".
Step 4

Remove the piece and wrap it into a towel. Roll the towel to wring out the excess water from the cotton garment.
Step 5

Stretch the item out to a desired size and secure it to a piece of cork board with thumb tacks.
Step 6

Allow the garment to dry. Periodically return to the cotton piece, remove the pins and re-stretch the piece, and replace the thumb tacks until thoroughly dry.
